This film cooling structure (1) has a wall surface (2) on which flows a heat medium, and at least a pair of film cooling holes (3a, 3b) that open into the wall surface (2) and that emit a coolant. The pair of film cooling holes (3a, 3b) are disposed adjacent to each other in the main flow direction of the heat medium. The directions of the openings of the pair of film cooling holes (3a, 3b) are set so that the directions of the coolant eddies formed by the above emission are in mutually opposite directions, and the eddy of the coolant on the downstream side of the main flow direction is pulled into and merges with the eddy of the coolant on the upstream side of the main flow direction, and this merged coolant flows along the wall surface in one direction which intersects the main flow direction. |
